MIAMI -

Pi Kappa Alphas at Florida International University offered no comment Thursday about the suspension of the fraternity chapter following a series of Facebook posts.

The university suspended the fraternity chapter after receiving an anonymous e-mail recently sent to local media and members of the FIU community included screenshots of Facebook posts that appeared to show fraternity members discussing the hazing of new members, which is prohibited by university policy. Posts also referred to drug use and made offers to sell drugs.

One post read, "On campus for those of you looking for the Pike Pharmacy." It also had a phone number listed. The Miami Herald reported calling the phone number, saying a man confirmed his first name matched the one from the post, then hung up.

Several posts were of half-nude women who had apparently dated fraternity members.

FIU said in a statement Wednesday that it is investigating possible violations of the university's code of student conduct. It said:

"Earlier this week, the University was made aware of Facebook postings which appear to be linked to the Pi Kappa Alpha fraternity Kappa Gamma chapter and members of the fraternity. The university is taking this information very seriously because it suggests possible Student Code of Conduct violations. The university took prompt action and placed the fraternity on interim suspension pending the outcome of investigations by appropriate university departments, including the police. As a result, the fraternity has been instructed to cease all meetings and events."

The Pi Kappa Alpha fraternity's national headquarters in Tennessee says the FIU chapter would fully comply with the temporary suspension and subsequent investigation.
